The type 4 engine uses a 215 mm clutch/pp package.
Clutch packs are usually matched to the bolt pattern on the flywheel.
Make sure that the clutch splines match the splines on the output shaft of the 915.
FWIW, a 912E uses a 923 trans mated to a type 4 lump.

Basically I’m trying to fit a 915 trans to a 914 type-4 engine in a rear engine car.

The 912e uses a push clutch, as far as I can tell, the only difference is the 912e has a different clutch fork, but otherwise the same trans other than gear ratio.

The clutch throughout bearing on the 912e is crazy insane expensive, so I’d like to use a 911 style pull clutch. 912e parts are next to impossible to find, way easier to source 911 parts.

So I’m trying to figure out what the flywheel depth is on the 911 engines and see if a 911 pressure plate would work with a type-4 flywheel.
